- the color ink lamp is the LED lamp 26
- the color ink lamp can be reduced in weight as compared with the case where the color ink lamp is a high-pressure mercury lamp, a metal halide lamp, or the like. Therefore, the inkjet printer 10 can reduce the size of the drive device for moving the carriage 23 on which the color ink lamp is mounted, and the entire inkjet printer 10 can be reduced in size.
- the high-pressure mercury lamp or metal halide lamp is less directional than the LED lamp.
- the ultraviolet rays irradiated by the high-pressure mercury lamp or metal halide lamp as the color ink lamp mounted on the carriage 23 are reflected on each part of the inkjet printer 10 or the print medium 90.
